Application filed November 14, 1923. SerialN o. 674,739.

To all whom it may cancer n Be it known that I, EMANUEL FOLGMAN, a

i citizen of theUnited States, and a resident ofthe city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a .new and Improved Torch, of which the following is a full, clear, and exact description.

The presentinvention relates to new and useful improvementsin' torches, andit pertains moreparticularly to torches of the selfblowing type. a

. Great difficulty. has heretofore been experiencedin torches of this type with a clogging or choking up of the gas or burner tube. A further disadvantage of this type of torch is the failure to properly function of the part of the-vent tubewhich relievesthe pressure from the fuel tank after the torch has been extinguished. 1 i i It is one of the primary objects of the invention to provide a torch in which the gas or burner tube may be readily} cleaned.

It is a further object of thelinvention to:

provide a vent tube of a new and improved type which will assure proper .relief-of the gases generated in the fuel chamber immediately after the torch has been extinguished.

It is a still further object of the invention to combine the gas tubeand the'vent tube in a single element, the" vent tube forming a means for conveying loosened particles of i any kind from the gastubetothefuel tank or reservoir.

With thea'bove'andother objects in view, reference is had to the accompanying draw ings, in which Figure 1 is a fragmentary view in front elevation of a torch constructed in accordance with the present invention;

Fig. 2 is a fragmentary sectional view thereof;

Fig. 3 is a fragmentary view in front elevation of a slightly modified form of the invention;

Fig. 4 is a fragmentary sectional view of the type of torch shown in Fig. 3.

Referring again to the drawings and more particularly to Figs. 1 and2, the reference numeral 5' designates the body of the torch, and as more clearly shown in Fig. 2, this body constitutes a reservoir for fuel 6., the fuel being of a liquid type and introduced into the body 5 through the medium of the opening closed by the plug 7. The reference numeral 8 designates a tube extending through the topwall 9 of the torch, and suchtube carriesa wick .10 and serves as a retort in a manner to be hereinafter described.

This tube is provided with a vent 11 which extends throughout the length of the tube 8.

Projecting upwardly from the top wall 9 of the body 5, there are two curved tubes 12, and carried by; each. of thetubes there is a wick- 13. The outer ends of the tubes 12 are preferablyhexagonal" in shape, as designated by thereference numeral 14, and screws, or the like, 15 are carried by each of thesehexagonal ends, the screws 15 being in alinement with each other. These screws. whenfremovedleave openings for the introduction of a suitable tool for cleaning the chamber at the end ofeach tube '12, and in which the gas isrformed.

Mounted preferably between the tubes 12 and on the exterior thereof, there is a tube 16. This tube 16 has its outer end closed by means of a screw 17 and its inner end projects throughthe top wall 9 of thebody 5 of the torch, as indicated by the reference numeral 18. Intermediate of its ends this tube is provided with an opening 19, such opening being positioned slightly above the top of the tube 8 and formed in. the, tube 16 in such a manner as to project gases'directly across the top of the wick 10 carried in the tube 8. The outer end of the tube 16, when it lies between the hexagonal ends 14; of the tubes 12, is provided with diametrically opposed openings 21,- and such openings are adapted to provide communication between the chamber formed in the end of each tube 12 and the tube 16.

The device functions in the following manner:

To start the torch the wick 10 is lighted and the flame thereof passes upwardly into engagement with the tubes 12. As the tubes 12 are heated, the liquid'fuel carried by the wicks 13 thereof is converted into gas and passes through the openings 21 in the tube 16 to the interior of the tube. From this point the gas passes down the tube 16 to the opening 19 and is projected across through the flame of the wick 10 where it is ignited. Due to the pressure under which this gas is discharged, the torch blows and continues to operate during the period which the wick 10 is ignited until the fuel is exhausted.

During the operation of the torch, a certain pressure is generated in the body 5 above the level of the fuel contained therein, and.

' T is action "is facilitate It is well known that certain depositsform" in-the tube 16 and upon jarring the torch these deposits are dislodged causing in prev-ious types cf torches,.a clogging of the tube 16. In the present device, however, the dislodged pmft i'cl'es 'are'rnoved through the tube by The JPHZSSEtg'B "of gas theret'hrough, and under the influence of gravity, the particles fall into the reservoir formed by the body 5, th is'pueventin-g a stoptpage in the tube 16.

by thefa'ct that the e16 is; free new sharpbends or turns and ,pas'saigetherethrougfhfis practically uninterrupted,

r11 hat a of the intention een in i and 4, "the improvement "is shown -as applied to a torch of the single tube type, and; in form of torch a ,gas tube 30 is positioned preferably beneath the wick tube 3 1,, and such Wick tube .31 is provided with a passage 32 which leads from c he chamber at the outer end 33 of thewick tube into the. gas tube 30. The gas tube 30 is provided with an opening '34 in proximity to the upper end of the wick t111be35'in'order'that gas in the ,gas "tube '30 may be projected'across carries a wick '36 and "is provided with a vent tube 37' of practically the same iform as that shown in the preferred type. In this form, of the invention the gas tube '30 projects 'be-' low the upper wall 9 of the body '5, as designated by the reterence numeral 37", and the operation is the same as in the preferred to m (If 'eirnvent-ion. The wick tuhe 31 in t"; 1n Offthe inventionis provided with anepeninge closed by a screw, or the like,

40, and such openingis diametrically opposed withrespectto the passage 32 inorder that a cleaning tool may be inserted through the opening 39 and the passage 32. The gas tube has its outer end closed by means of a screw 41, which when removed permits of the insertion of a. cleaning tool to the gas tube 30. Fromth'e roregoingit is apparent that the present invention provides a new and im-. proved torch in wliichthe passages maybe readily cleaned and infwhich the passages are of such shape-and construction that the lodging of particles and a resultant clogging of the passages, is ebvi'ated' What is claimedrisz.
